56. Select the Exposure time red parameter and set the exposure time for the red chan-
nel to achieve a high, non-saturated exposure for the red channel.
57. Select the Balance green parameter and adjust the value until the red and green
profiles in the Profile zoom window match.
58. Select the Balance blue parameter and adjust the value until all three profiles match.
When adjusting the exposure times, watch the log for warning messages indicating that
the efficient exposure time for any color is longer than the cycle time. If this should happen
try the following:
 Increase the cycle time to allow the longer exposure time.
 Decrease the exposure time of the red reference channel.
 Increase the gain of one or more channels so that the exposure time can be decreased.
The shortest possible exposure time for each color channel is approximately 50 microsec-
onds.
It is also sometimes a problem to have exposure times very close to the cycle time.
If it is difficult to achieve a proper white balancing, consider using a light source that better
matches the specifications of the sensor and the color filters, as described in chapter
9 “Hardware Description”.
